Fresh and dried herbs are not interchangeable one-for-one — drying concentrates flavor. The rule of thumb is three parts fresh to one part dried. Some herbs also simply work better dried than others.
| Herb | Dries well? |
|---|---|
| Oregano | Yes, excellent |
| Thyme | Yes |
| Rosemary | Yes |
| Bay leaf | Yes (almost always dried) |
| Sage | Yes |
| Basil | Fair — loses aroma |
| Parsley | Poor — weak dried |
| Cilantro | Poor |
| Chives | Poor |
The 3-to-1 rule: 1 tablespoon fresh chopped herb equals about 1 teaspoon dried. Add dried herbs early so they rehydrate; stir fresh herbs in near the end to keep their aroma.
